Fig. 2From: A case report of spontaneous rupture of intracranial epidermoid cyst with dramatic increase of serum carbohydrate antigen 199: a three-year follow-up studyFollow-up of the patient. MRI scans half a month post-surgery (a, b), one month post-surgery (c, d), half a year post-surgery (e, f) and one and half a year post-surgery (g, h) showed that the size of residual tumor decreased gradually, which correlated with the trend of decreased value of CA 199 (k). While the latest MRI scan three years post-surgery (i, j) showed an enlargment of the lesion in the left anterior cranial base, consistently, the value of CA 199 raised up from 41.7U/ml to 47.0 U/ml.
